Description

Technical Field

[0001] The utility model relates to a powder material conveying device, in particular to a split-flow vibrating spreading powder material conveying device. Background Art

[0002] When mixing and conveying powders with poor fluidity or high solid content, caking is likely to occur, resulting in uneven mixing. Figure 1 As shown, currently, a vibration device is used to directly vibrate the powder 100 so that the powder 100 is spread and transported forward. However, this vibration flat structure has the problem that the powder dropped from the outlet of the storage tank onto the vibration plate 1 will pile up, and in the process of vibrating and transporting forward, the powder will be spread in blocks, and the uniformity is poor, resulting in low quality of the output powder, which is easy to fail to meet the requirements. Utility Model Content

[0003] The purpose of the utility model is to provide a split-flow vibrating spreading powder conveying device to solve the above problems. The device splits the powder into multiple flow channels and simultaneously vibrates and spreads the powder in the multiple flow channels to achieve a more uniform spreading purpose.

[0004] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0005] A split-flow vibrating spreading powder conveying device, comprising

[0006] Vibrating plate, used to carry powder;

[0007] A vibration device, used to drive the vibration plate to vibrate, so that the powder is spread and transported forward;

[0008] As a preferred solution, the vibrating plate is provided with a dividing member for dividing the powder into a plurality of powder flows.

[0009] As a preferred solution, the dividing member gradually separates the powder into a plurality of powder flows, and the number of the powder flows gradually increases along the flow direction of the powder.

[0010] As a preferred solution, the number of the dividing members gradually increases along the flow direction of the powder.

[0011] As a preferred solution, along the flow direction of the powder, the dividing elements are arranged in multiple layers, and the number of dividing elements in the next layer is greater than that in the previous layer.

[0012] As a preferred solution, along the flow direction of the powder, the dividing members of the next layer will divert the powder delivered from the dividing members of the previous layer to form at least twice the powder flow.

[0013] As a preferred solution, the lower layer of the baffle is arranged at the powder outlet of the upper layer of the baffle.

[0014] As a preferred solution, the number of the lower layer of the baffle is set to be twice the number of the upper layer of the baffle.

[0015] As a preferred solution, the baffle is a bent baffle strip, and the arching direction of the convex part of the bent baffle strip is opposite to the flowing direction of the powder.

[0016] As a preferred solution, the bent baffle strip is in the shape of "7", or triangle, or arc.

[0017] As a preferred solution, side guiding members for guiding the powder to flow towards the middle position are arranged on the inner walls on both sides of the vibrating tray.

[0018] As a preferred solution, the side guiding member is a guiding plate arranged obliquely downward along the flowing direction of the powder, and the upper end of the guiding plate is connected to the inner side wall of the vibrating tray.

[0019] Implementing the present utility model has the following beneficial effects:

[0020] 1. During operation, the powder falling from the storage tank is conveyed forward under the action of the movement of the vibrating tray; during the forward conveyance process, the powder is separated into multiple powder flows by the baffle, that is, the powder is shunted into multiple powder flows, so that the powder is evenly spread out into multiple powder flows for flowing, and at the same time, it is more easily and evenly spread out under the vibration of the vibrating tray, with high uniformity and no blocky distribution. It can be seen that this structure adopts the method of shunting the powder into multiple flow channels and vibrating and spreading the powder in multiple flow channels simultaneously to achieve a more uniform spreading purpose.

[0021] 2. The present utility model gradually separates the powder into multiple powder flows, enabling the powder to be gradually spread out into multiple powder flows, thereby achieving the purpose of more uniform shunting and spreading of the powder. If the powder is separated into multiple powder flows at one time, there will be a large difference in the powder flow rate of multiple powder flows, which may lead to poor effect of vibrating and spreading the powder in multiple powder flows by the vibrating tray, resulting in poor spreading uniformity. Therefore, compared with the structural design in which the baffle separates the powder into multiple powder flows at one time, this structure has the advantages of higher spreading uniformity and stability.

[0022] 3. The present utility model arranges the baffle in a layered structure, enabling the powder to be more evenly and orderly shunted and spread. During the forward conveyance process of the powder, the powder is gradually separated into multiple corresponding and neatly arranged powder flows, so as to ensure that the vibrating tray can effectively vibrate and spread multiple powder flows simultaneously, achieving the effect of uniform overall paving.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] Embodiment

[0029] Refer to Figure 2 and Figure 3 This embodiment relates to a powder conveying device with a shunt type vibration spreading, including a vibrating tray 1 for carrying the powder 100, and a vibration device (shown in the figure) for driving the vibrating tray 1 to vibrate so as to spread and convey the powder forward; a baffle 2 for separating the powder into multiple powder flows 101 is provided on the vibrating tray 1.

[0030] During operation, the powder falling from the storage tank is conveyed forward under the driving action of the vibrating tray 1; during the forward conveying process, the powder is separated into multiple powder flows 101 by the baffle 2, so that the powder is evenly spread into multiple powder flows 101 for flowing, and at the same time, under the vibration of the vibrating tray 1, the multiple powder flows 101 are more easily evenly spread, with high uniformity and no blocky distribution. It can be seen that this structure adopts the method of shunting the powder into multiple powder flows and vibrating and spreading the multiple powder flows simultaneously to achieve the purpose of more uniform spreading.

[0031] The baffle 2 gradually divides the powder into multiple powder streams 101. Along the flowing direction of the powder, the number of the powder streams 101 gradually increases. By gradually dividing the powder into multiple powder streams 101, the powder can be gradually spread out into multiple powder streams 101, thereby achieving the purpose of more uniform diversion and spreading of the powder. If the powder is divided into multiple powder streams 101 at one time, there will be a large gap in the powder flow rates of the multiple powder streams 101, which may lead to poor vibration spreading effect of the vibrating disk 1 on the multiple powder streams 101 and poor spreading uniformity. Therefore, compared with the structural design in which the baffle 2 divides the powder into multiple powder streams 101 at one time, this structure has the advantages of higher spreading uniformity and stability.

[0032] Along the flowing direction of the powder, the number of the baffles 2 gradually increases. By increasing the number of the baffles 2, the powder is gradually divided into more and more powder streams 101, achieving the effect of uniform diversion and spreading of the powder.

[0033] Along the flowing direction of the powder, the baffle 2 is arranged in multiple layers, and the number of the baffles 2 in the lower layer is more than that in the upper layer. The baffle 2 is arranged in a layered structure, so that the powder can be diverted and spread more uniformly and orderly. During the forward transportation process of the powder, the powder is gradually divided into multiple corresponding and neatly arranged powder streams 101, thereby ensuring that the vibrating disk 1 can effectively vibrate and spread the multiple powder streams 101 at the same time, achieving the effect of uniform overall paving.

[0034] Along the flowing direction of the powder, the baffle 2 in the lower layer diverts the powder transported from the baffle 2 in the upper layer to form at least twice as many powder streams 101. Each baffle 2 in the lower layer re-diverts each powder stream 101 flowing out from the baffle 2 in the upper layer into at least two powder streams 101, achieving the purpose of gradual diversion, thereby spreading the powder more uniformly.

[0035] The baffle 2 in the lower layer is arranged at the powder outlet 21 of the baffle 2 in the upper layer. By arranging the baffle 2 in the lower layer close to the powder outlet 21 of the baffle 2 in the upper layer, the powder transported from the baffle 2 in the upper layer can be quickly re-diverted and spread, improving the spreading speed and efficiency, and reducing the length of the vibrating disk 1, having the advantages of high working efficiency, reducing the equipment volume and lowering the manufacturing cost.

[0036] Preferably, the number of the baffles 2 in the lower layer is set to be twice that of the baffles 2 in the upper layer. Each baffle 2 in each layer re-divides each powder stream 101 transported from the baffle 2 in the upper layer into two powder streams 101, presenting a process of uniformly and gradually increasing the powder streams 101 such as 1, 2, 4, 8, 16..., having the advantages of more uniform and stable diversion and spreading.

[0037] The grading member 2 is a bent retaining bar, and the arching direction of the convex portion 22 of the bent retaining bar is opposite to the flowing direction of the powder material. The convex portion 22 of the bent retaining bar serves as a flow splitter, which resplits each powder material flow 101 conveyed from the powder material outlet 21 of the upper-layer bent retaining bar to both sides, achieving the effect of gradually increasing the powder material flow 101.

[0038] The bent retaining bar is in a "7"-shaped configuration, or a triangular configuration, or an arc-shaped configuration. As Figure 1 shown, the bent retaining bar is set in a "7"-shaped configuration; at this time, the bent retaining bar is an angle iron, and its sharp angle is close to the outlet of the upper-layer bent retaining bar. As Figure 2 shown, the bent retaining bar is set in an arc-shaped configuration, and the arching direction of its arched portion is opposite to the flowing direction of the powder material; at this time, the arched portion is close to the powder material outlet 21 of the upper-layer bent retaining bar. If the two ends of the "7"-shaped bent retaining bar are connected, the bent retaining bar forms a triangular configuration at this time.

[0039] Side guiding members 3 for guiding the powder material to the middle position are provided on the inner walls on both sides of the vibrating tray 1. Side guiding members 3 are provided on both sides of the grading member 2 of the first layer, while side guiding members 3 may not be provided on both sides of the grading members 2 of other layers. During the process of the powder material falling from the outlet of the storage tank and being conveyed forward, the side guiding members 3 guide the powder material to the middle of the vibrating tray 1, so that the powder material close to the sides of the vibrating tray 1 can be split and spread out by the grading member 2 of the next layer, improving the uniformity of spreading.

[0040] The side guiding member 3 is a guiding plate inclined downward along the flowing direction of the powder material flow 101, and the upper end of the guiding plate is connected to the inner side wall of the vibrating tray 1. The guiding plate with this structure can guide the powder material located at the side position of the vibrating tray 1, so that the powder material is guided to the middle of the vibrating tray 1 and is split and spread out by the grading member 2 of the next layer.

[0041] The above-disclosed is only a preferred embodiment of the present utility model, and of course, it cannot be used to limit the scope of rights of the present utility model. Therefore, equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
